CSJ Crown Drill Bit, 4D Drill Diameter Range 23.00-23.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

 Short Description

The CSJ Crown Drill Bit is a high-performance 4D indexable insert drill engineered for high-speed, deep-hole applications. Featuring a robust front-locking body, an advanced side-locking drill tip design, and an integrated internal cooling system, it delivers exceptional chip evacuation, superior hole accuracy, and extended tool life in demanding manufacturing environments.

 Product Introduction

Designed to meet the rigorous demands of modern CNC machining, the CSJ Crown Drill Bit (4D) combines the rigid stability of a solid carbide drill with the cost-efficiency of indexable inserts. Its innovative front-locking body secures the side-locking crown tip seamlessly, drastically reducing vibration during high-speed operations. Equipped with dual internal coolant channels, this tool ensures precise fluid delivery directly to the cutting edge, effectively minimizing thermal stress and maximizing productivity in deep-hole drilling.

Technical Parameters

 Product Functions & Benefits

• High-Speed Deep-Hole Drilling: Easily achieves a 4D drilling depth with stable performance and minimal deflection.

• Internal Cooling Technology: The specialized through-coolant channels flush out chips instantly and lower cutting temperatures, preventing premature insert wear.

• Rigid Locking System: The combination of a front-locking body and a side-locking tip provides maximum structural integrity, ensuring high repeatability and excellent surface finish.

• Cost-Efficient Indexable Design: Eliminates the need for regrinding. Simply index or replace the crown tip to maintain optimal cutting edge sharpness, reducing downtime.

 Target Applications & Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty manufacturing sectors, including:

• Automotive & Aerospace: Drilling engine blocks, transmission components, and structural frames.

• Mold & Die Manufacturing: Creating deep core cooling channels and guide pin holes with strict tolerances.

• Heavy Machinery: Processing large flanges, tube sheets, and pressure vessels.

• General Engineering: High-efficiency batch hole-making on CNC vertical/horizontal machining centers and lathes.
